Letters Patent No. 110,796, dated January 3, 1871.

IMPROVEMENT IN HYDRAULIC ENGINES.

The Schedule referred to in these Letters Patent and making parl: o the same.

To all'whom it may conce/rn;

Be it known that I, WILLIAM Sxvpnn, of Bullskin towns'hip, in the county of Fayette and State ot' Pennsylvania, have invented a new and valuable Improvement in Hydraulic Engines; and I do hereby declare that the following is a full, clear, and exact description ofthe construction and operation of the same, reference being had to the annexed drawing making a part of this specification, and to the letters and figures of reference marked thereon.

Figure 1 of the drawing is a representation of eugine in perspective, arranged for vertical operation.

Figure. 2 is a perspective view of engine, arranged for horizontal operation. f

Figure 3 is a vertical section of Iig. I.

Figure 4 is a perspective view of vertical shaft and wheels.`

My invention relates to the general improved construction and arrangement of hydraulic engines in their application for the purpose of operating mills and machinery through-.the motive power of water, the' percussive force being received on properly-constructed wheels, which thereby revolve and transmit 'motion by means of suitable gearing or connections.

The device forming the subject matter of the present invention is designed to operate with the 'axis ot' motion of the wheels, either horizontal or vertical.

A Figs. 1 and 3 in the drawing represent clearly and correctly the arrangement of the engine for vertical operation, the different parts being, in general construction, the same as for horizontal arrangement.'

A represents a cylinder of proper proportions, provided with a forebay, B, of ordinary construction, for the entrance of water, and capable of ready attachment to sluiee-outlets.

C represents the bay-gate sliding vertically.

D shows the vertical wheel-shaft, to which are keyed the wheels E, one above and. one below the bay B, with their vanes inclined toward the opening thereof.

F is a seat for the lower end of the shaft to turn on, formed of two cross-bars rigidly fixed within the cylinder below the forebay.

G is an oval plate covering a man-hole inthe cylnder near the forebay. p

This plate is secured in place by the screw-rod g, which passes through the curved bar h, and held by a nut, h.

The purpose ofthe man-hole is to allow of the easy removal of obstructions accumulating between the wheels.

H represents an outlet-sluice connected by bolts with the hanged rim on the upper end of thecylinder, and thence taking a vertical descent, as shown in iig. l.

After impinging on the wheels, the water passes ottthrough the sluice H and-lower end of the cylinder.

The vertical shaft D passes through a box, d, formed in top of the sluice H, 'and is geared or properly connected with such machinery as it 'is' designed to 0pcrate.

d represents a bushing, secured inV place by bolts and screws, the latter being inserted in the sluicetimbers.

I represents the timbers by which the engine may be secured by bolts to its foundation.

' Fig. 4 illustrates the mode kof' arrangement ot' thc engine for obtaining horizontal motion.

For this purpose the section of' the cylinder containing the seat of the vertical shaft is removed, as also is the sluice H. v

A straight sluice, HI, is substituted for the latter, and one similar' thereto attached to the other end ot' the cylinder. l i

A longer shaft, H2, with gudgeons-at both or one end only, issubstituted for the vertical shaft. The

engine is then properly arranged.

'lhewater enters the forebay and passes oII through the vertical sluices or boxes H1. l

'lhe gate C of the fore-bay is provided with cleats c c, by means of which it is larranged to slide on the square frame which surrounds the mouth of the forcbay. The gate is'reversible, and, can, therefore, be used with either position of the casing.

\ C' latin. lThe hydraulic engine, having cylinders A, fore-bay 'B, man-hole covered by plate G, shaft I) with wheels E, step F, and sluice H, constructed as described, and adjusted for operation as specified.

In testimony that I claim the above, I have here-v unto subscribed my name in the presence of two wit nesses.

Witnesses:

I. LLOYD SHALLENBERGER, HENRY JORDAN.
